Hello,I completely uninstalled version 5.5.1. running downloaded set-up for version 5.5.3. and getting still the same error0x800700e8.....I tried everything / two recommended cleaning windows utilities from support page. bought and run Special uninstaller then also PC scan and Repair.There are no signs of anything which would be left after uninstallation.... however if I want to install a new version still getting the same error.Any idea ?many thanks !

Thanks, I'll start digging into them - though I expect I won't finish today (getting bed time soon for an old guy like me)

It does look like the error occur when it tries to get admin rights, so can you please let me know:

1) Do you get the dialog where Windows ask if the installer can get admin rights to make changes to your system?2) If you run the installer by right clicking and selecting "Run as administrator" do you get the exact same error? - if not, please collect the new log file the same way you did for the files I already got.3) What antivirus program are you running? It seems AVAST might be throwing a false alarm on EditVoicepack 5.5.3 so it might stop it- it happens now and then.

many thanks for support !I run it by right clicking - as administrator and the error window is the same.The set-up installer starts, then few seconds nothing and then the window with the error message.Yes, I use Avast. I set up in exclusion the installer. I did the same also with previous versions....JM

As far as I can see on https://www.virustotal.com/ the 5.5.3 installer is not showing a false detection from Avast anymore, so please try it again.

I am not sure how you excluded the installer? The installer will unpack the MSI on disk and then launch a new process to do the actual installation. So if the exclusion was made based on file name or process name, it might not cover the launched install process.
